Based on the Original Ball Pocket Watch

Jeweler Webb C. Ball created the original Cannonball pocket watch after a tragic miscommunication on the railways in Ohio in 1891. It established the Official Railroad Standard, which has been closely tied to the Ball Watch Company ever since. The Trainmaster Cannonball is filled with homages to that iconic timepiece, including a prominent diamond-shaped crown, vintage Arabic numerals, squélette hands, and a straightforward 60-second subdial. However, this model is easy to read at night, too, thanks to tritium pips at every hour and in the hands. Powered by a Ball RR1401-SL 25-jewel automatic movement, it boasts a 42-hour power reserve and is water resistant to 50 meters.
